.6 lllaims, (Cl. 106-9) The object of my invention is to provide a polish and cleaner for metal and wooden sur= faces in particular, and for surfaces of certain other materials such as fabric, which will give to such surfaces an attractive and durable satin finish. Another object of the invention is to provide a polish which, when applied to metal surfaces, such as steel, steel alloys and other metals, that are susceptible to rust, will prevent the formation of rust, or definitely arrest any rusting that has occurred. A further object of the invention is to provide a polish that is non-infiamusable, either in bulk or when spread as a thin. film over the protected surface and which will have the qualities above specified under conditions of prolonged exposure to sun or rain or salt-laden fog. A still further object of the invention, particularly useful as applied to surfaces of wood or fabric, is to provide a polish that will resist penetration of grime and from which any superficial dust or dirt may be readily removed.

The composition comprises a moisture-free solution of dehydrated rat fish liver oil, which is not processed to eliminate any of its natural constituents other than insoluble solids, and a light hydrocarbon oil, preferably that fraction of petroleum having a boiling range substantially that of kerosene, and therefore including hydrocarloons boiling from somewhat less than 400 F. up to somewhat over 500 F. These two oils, when mixed, and without special treatment, form a true solution, as distinguished from an emulsion.

The proportions of the two constituents may vary from eight parts of the fish liver oil to from one part to forty parts of the hydrocarbon oil. The preferred range of proportions is one part of the fish liver oil to between two to three parts of the hydrocarbon oil.

It is possible, if the hydrocarbon oil is a petroleum fraction, to utilize, in place of kerosene, a lighter fraction such as gasoline, having a boiling range of about 80-400 F., or a somewhat heavier fraction such as a gas oil fraction having a boiling range of from about 440 to above 760 F. and thus including fractions somewhat heavier than, and the heavier fractions of, kerosene; but I have found kerosene to give the best results.

The fish oil that I have found essential must be, at least mainly, fish liver oil, and I have found that liver oil obtained from rat fish gives distinctly superior results. The fish liver need not be specially processed except to the extent of removing any insoluble solid constituents and of effecting as far as possible its substantially complete dehydration. The presence of any substan-= tial moisture in the solution imparts to it certain qualities which make it impossible to attain the principal objects of the invention. The complete exclusion from the composition of fish oil other than fish liver oil or of other animal or vegetable oil is not essential, but such addition must be in distinctly minor proportion and such addition, to the extent that it is added, will reduce the efficiency of the compo- SltlOi'i.

The solution does not have a particularly dis-- agreeable odor, but I prefer to add to it a very small proportion of synthetic oil of wintergreen..

Kerosene when spread over any surface in a thin coating or film, is inflammable, but a solution embodying my invention is not inflammable unless it contains an excessive proportion of hero-- sen'e. To insure absolute protection from fire, the ratio of kerosene to fish liver oil should not much exceed the preferred ratio range hereinbefore specified.

The solution should be applied to the surface to be polished with a dry cloth. A wet cloth cannot be safely used. After application of the solutionit, may be finished with a dry lintless cloth. After the polish is definitely set it may be cleaned from time to time with a wet cloth, since the coating of polish is only slightly permeable by water.

A small volume of the solution will suffice to cover and protect a comparatively large surface. Thus, one of its principal uses is its application to automobile bodies. A very thin film will suffice to prevent rust, arrest rusting that has already occurred, and render the surface impermeable to moisture. Between one and two ounces of the solution sufl'ices for the entire body. After its application in the manner above recommended, the surface presents a very sightly dull satin finish. Even if applied to a very old car, the polished body presents the appearance of a new body. The polish is so durable that renewal is not required for a long period of time. If the automobile is new, protection against rusting is insured. If the car is an old one and if rust spots or streaks have developed, the application of the polish to the rusted surfaces renders the same less readily observable and insures against spreading of such spots or streaks or the development of new areas of rust.

Automobiles that are maintained in, or traverse, areas near the seashore are especially susceptible to rusting by subjection to salt-laden air, particularly to fees holding salt in suspension or 3 solution. I have found that my new composition effectively protects the metallic body, as well as chrome-plated or ferrochrome elements such as door handles, from the commonly destructive effects of such atmospheric conditions.

The composition can be applied with notable advantage not only to other metal structures or articles but also to furniture and other articles of wood, or to any wooden surfaces such as floors. The solution seals the wood against penetration by grime, and any dust or dirt that may collect on the polished surface may be readily removed.

While the polish is particularly intended jor application to metal and wood, it is also applicable to fabric. It is not recommended fprglass as the film adheres so tenaciously, making it difficult to polish clear.

While other ingredients, such as, for example, synthetic oil of Wintergreen, may be added/to the solution in minor proportions, the solution must be free of any added constituent having a substantial water content or any added ingredia ent which afiects the solubility of the two essential constituents, as, for example, any ingredient which would convert the solution into an emulsipn, or which has a substantial moisture con.- tent, (or which afiects the resistance of the solution to moisture.

What I claim and desire to protect byLetters latent 1. A polishing composition the major constituent, at least, of which consists of a substantially moisture-free solution of rat fish liver .oil and a light hydrocarbon liquid in the proportion by volume of eight parts of the hydrocarbon l quid to irom one to forty parts of the rat fish liver oil.

2, A polishin composition the major constituent, at least, of which consists of a substantially mqisture free solution of rat fish liver oil and s, igh h oc bon liquid in the propo tion y volume of from about two to three parts of the hydrocarbon liquid to one part of the rat fish liver oil.

3. ,A polishing comp sition comprising as its ain in re a sub tan ia moistu e-tree solution o ei t pa ts by vol me or rat fis live oil and from one to forty parts by volume of a petroleum fraction having a boiling range mainly within that of kerosene.

4. A polishing composition comprising as its main ingredients a substantially moisture-free solution of one part by volume of rat fish liver oil and from about two to three parts by volume of a petroleum fraction having a boiling range mainly within that of kerosene.

5. A polishing composition comprising a moisture-free solution of rat fish liver oil and a light hydrocarbon liquid, the latter named being in major proportion and the first named constituting at least the major proportion of the remainder of the composition.

6. A polishing composition comprising a mois- -ture- I "ree solution of rat fish liver oil and a petroleum fraction Within the boiling range of gasoline, kerosene and gas oil, the hydrocarbon liquid being present in major proportion and the rat fish liver oil constituting at least the major proportion of the remainder of the composition.
